I have used Wiseco on many a two stroke, never a problem. Very fine pistons. I put a forged one in my 06 yz450. It got a lot louder in that plinking, tapping sound at idle. The engine is noisier now than ever. All the clearances checked out. Something about the forged piston I was told increases the noise. Works good though, it's been in there for a year and no trouble. Probably 20 hours or so.
